All that we can say for certain is that there definitely seems to be a lot of it about.

A magnificent 300 foot long 'crop circle' that seems to depict the Holy Grail has appeared in mysterious circumstances in a field close to the Avebury stone circle in Wiltshire.

The crop formation was spotted at about 3 am by investigators who were watching the fields in the area hoping to catch the circle makers at work. The researchers, equipped with night vision glasses, were astonished to find the circle had appeared in a field they had been watching just an hour and a half earlier when they returned after checking other fields in the area.

The formation appears to represent the Holy Grail, a sacred object in many Christian traditions, most often identified with the cup used by Jesus at the Last Supper, and is supposed to possess miraculous powers.

Steve Alexander, a crop circle photographer for many years said 'This is the third formation this year to relate to Jesus Christ. Only last month two circles straddling the M4 appeared to represent the face of Jesus Christ on the Turin Shroud. There has also been a crop formation representing a crucifix close to the Avebury stone circle, which has been the centre of crop circle activity for many years now.'
